What is a system actor? Someone who develops a system. A mechanical component of the system, like a personal computer or other device. A human or external entity that interacts with the system. A computer process, e.g. a program, that 'acts' (performs a function) inside the system to produce a result.

What does a use case diagram depict? How data flows through a system or application. A system actor performing an action by interacting with the system. The system state. The relationship between various system actors.

A use case diagram depicts a system actor performing an action by interacting with the system.

What is the difference between a use case diagram and an activity diagram? A use case diagram shows how one activity using the system leads to another. An activity diagram shows how actors interact with the system. A use case diagram shows how system actors interact inside the system boundary. An activity diagram shows how system actors interact outside the system boundary. A use case diagram shows how actors interact with the system. An activity diagram shows how one activity using the sytem leads to another. An activity diagram shows how system actors interact with each other. A use case diagram shows how use cases interact with the user.

A use case diagram shows how actors interact with the system. An activity diagram shows how one activity using the sytem leads to another.

Conceptual modeling

Which of these steps is part of the guiding principle of risk management? Creating contingency plans. Delivering quality in all steps. Trusting in your colleagues. Listening to a focus group.

Creating contingency plans. Risks are a part of any business process, including software engineering. Creating contingency plans can help you assess risks and be prepared for them.

Which of the following is NOT one of the six selection characteristics used to identify classes to be included in the model? External entities Multiple attributes Retained information Common operations

External entities

What is the first step in software prototyping? Develop the prototype Beta testing Identify initial requirements Evolutionary

Identify initial requirements

Which of the following is NOT a characteristic of Requirement Engineering? Documenting Capabilities a system will incorporate. Important to the overall system. Identifying Risks a system will address. Enumerating Capabilities a system will incorporate.

Identifying Risks a system will address.

Collaboration is _____ to Requirements Engineering. None of the answers are correct. Useless Unrelated Important

Important

Another term for data modeling is: Logical modeling Information modeling Conceptual modeling Physical modeling

Information modeling

Why is change management important? To accept potential risks and create back-up plans. It helps develop a process for analysis and incorporation of change requests. It ensures delivery of value in the end result for consumers. To move swiftly and maintain flexibility internally.

It helps develop a process for analysis and incorporation of change requests.

At what stage are data attributes and relationships defined? Conceptual modeling Logical modeling Physical modeling Scenario-based modeling

Logical modeling

The term ''multiplicity'' in the context of class-based modeling means: A group of classes with the same attributes. Many instances of the same class. A class that is dependent on another class. Many instances of a class having a relationship of the same type with another class.

Many instances of a class having a relationship of the same type with another class.

Which of the following is NOT an element of the Requirements Model? Validation Solicitation Marketing Analysis

Marketing

A grammatical parse underlines which parts of the problem statement or use case: Nouns and noun clauses Adjectives Verbs only Verbs and nouns

Nouns and noun clauses

Which of these stages of modeling describes the structure of a database in full detail? Conceptual modeling Logical modeling Physical modeling Requirements modeling

Physical modeling

Which of the following is NOT an element of UML models? Package Node Program Note

Program UML model diagrams consist of the following basic elements : Class, object, interface, collaboration, use case, note, node and package.

In the principles that guide process, this component should be the main focus at every step, activity, action, and task. Communication Agility Team-building Quality

Quality

In which phase of software engineering are UML models used? Requirements modeling phase Requirements collection phase Deployment phase Requirements analysis phase

Requirements modeling phase UML is a pictorial language consisting of symbols, diagrams, text, pseudo-code or anything that describes a software system. UML models are particularly used in the requirements modeling phase to model software systems.

The validation of requirements is done through _____. Outcomes Reviews Calculations Analysis

Reviews The validation of requirements is done through reviews.

Which of the following stages is NOT part of data modeling? Physical modeling Scenario-based modeling Logical modeling Conceptual modeling

Scenario-based modeling

While there is no 'right way' of proceeding through requirements modeling for software engineering, which stage does it typically begin with? Flow-oriented modeling. Scenario-based modeling. Class-based modeling. Behavioral modeling.

Scenario-based modeling Requirements modeling typically begins with scenario-based modeling, to develop the use cases that are referred to by the ensuing stages of the process.
